Tributos indiretos na cadeia produtiva do camarão

The state of Rio Grande do Norte counts with a relevant potential in the shrimp farming supply chain. In the larviculture step the state responds for more than half of the national production. In the farming step it is the second largest producer. In the industrial step, its industries have almost 40% of the shrimp processing capacity of the northeast of Brazil. However, this country has the highest tax rate comparing with the main shrimp producer countries. Considering the influence of taxes in the competition among companies, the main goal of this research is to analyze the impact of indirect taxes in the above steps of the supply chain. To achieve it, it will be used the data of the 2011 Census of the Shrimp Farming and it will be applied the Herfindahl-Hirschman Index to identify the market form of those steps. In order to contribute with the characterization of the supply chain, CEO´s of farms and industries will be interviewed. The price-elasticity of the shrimp larvae, the in natura shrimp and the processed shrimp will be analyzed in order to verify the possibility that each one of those three steps has to pass-through the onus of the end of benefit over the ICMS. The data analysis shows that the larviculture step functions as a duopoly and, facing the end of that benefit, it will be able to pass-through most its onus to the farming step. On the other hand, this step functions similar to a perfect competing market, which diminishes its capacity to pass-through that onus to the processing step. This step operates as oligopoly with a lower concentration than the larviculture step but, due to the fact that it faces an oligopsony, it will end up assuming most of that onus, which will cause a decrease in the amount of processed shrimp. It is concluded that the end of that benefit would impact negatively, in this state, the supply chain at all, but mainly the farming and the industrial steps

Teoria de carteiras e a alocação de parques eólicos offshore

The consumption of energy on the planet is currently based on fossil fuels. They are responsible for adverse effects on the environment. Renewables propose solutions for this scenario, but must face issues related to the capacity of the power supply. Wind energy offshore emerging as a promising alternative. The speed and stability are greater winds over oceans, but the variability of these may cause inconvenience to the generation of electric power fluctuations. To reduce this, a combination of wind farms geographically distributed was proposed. The greater the distance between them, the lower the correlation between the wind velocity, increasing the likelihood that together achieve more stable power system with less fluctuations in power generation. The efficient use of production capacity of the wind park however, depends on their distribution in marine environments. The objective of this research was to analyze the optimal allocation of wind farms offshore on the east coast of the U.S. by Modern Portfolio Theory. The Modern Portfolio Theory was used so that the process of building portfolios of wind energy offshore contemplate the particularity of intermittency of wind, through calculations of return and risk of the production of wind farms. The research was conducted with 25.934 observations of energy produced by wind farms 11 hypothetical offshore, from the installation of 01 simulated ocean turbine with a capacity of 5 MW. The data show hourly time resolution and covers the period between January 1, 1998 until December 31, 2002. Through the Matlab R software, six were calculated minimum variance portfolios, each for a period of time distinct. Given the inequality of the variability of wind over time, set up four strategies rebalancing to evaluate the performance of the related portfolios, which enabled us to identify the most beneficial to the stability of the wind energy production offshore. The results showed that the production of wind energy for 1998, 1999, 2000 and 2001 should be considered by the portfolio weights calculated for the same periods, respectively. Energy data for 2002 should use the weights derived from the portfolio calculated in the previous time period. Finally, the production of wind energy in the period 1998-2002 should also be weighted by 1/11. It follows therefore that the portfolios found failed to show reduced levels of variability when compared to the individual production of wind farms hypothetical offshore

Análise da gestão da cadeia de suprimentos de um supermercado varejista através da utilização do modelo SCOR

In the last decade the complexity of the environment in which organizations are embedded increased dramatically, having on one side the increasingly demanding consumers in regard to the quality and value of the product and the other companies with the need to reduce operating costs in order to achieve greater profitability, without this there is a downturn in growth or market share powers. In this context the necessity of effectively structuring actions relating to the line with the operational work processes so that business objectives are achieved organizational strategic planning, ensuring the competitiveness of the organization. This study aims to analyze how you have made the management of the supply chain in a grocery retailer in the light of guidelines of Supply Chain Management by using the SCOR model. For realization of this study a survey was needed, classified according to their goals, exploratory and descriptive as to its procedure, document, field and case study. Thus, the processing of data will be qualitative merit, using the thematic categorical analysis of Bardin (1977). Thus, to obtain data interviews together the operational and strategic management of a company that was named Supermarket Omega were performed. After analyzing the information obtained is perceived that there is an effort of the organization enhance its management of the supply chain. However, there is a lack of alignment between the various areas that compose it. About their work processes, we stress that the focus of the company is still very directed on sailing than profitability, although it is undergoing a transformation in its organizational culture However, records the existence of many improvement projects in developing. Thus, it can be noticed that there is some consistency between the assumptions of the SCOR model and applied within the supply chain Omega Supermarket, although a greater effort to better align with the model still needs to be studied

A liderança e suas relações com o comprometimento organizacional

This study presents the results of field research of an exploratory descriptive character that seeks to identify the latent dimensions of leadership and organizational commitment as well as to discover the relationship between these two sets of indicators. In the study, 236 respondents were interviewed, 84 being managers or owners and 152 being sales personnel. The research was undertaken in five shopping centers in the municipality of Natal, capital of Rio Grande do Norte, and employed two different questionnaires. One of them was developed by Bass and Avolio, 1992 (in NORTHOUSE, 2004), contained 21 indicators of leadership and was completed by store managers. The other instrument, completed by sales personnel in the stores, was developed by Medeiros, Albuquerque, Marques and Siqueira (2003) and contained a total of 28 indicators of organizational commitment. For the analysis of the data, factor analysis techniques and structural equations modeling were used. Using the factor analysis, five dimensions of leadership and seven dimensions of organizational commitment were found, all of which have a theoretical basis for their explanation. Through the structural equations modeling, a relationship was established between leadership and organizational commitment, in which it was possible to observe that certain leadership styles influence in a positive form the commitment of the employee

Processo de implantação de um sistema integrado de gestão em uma organização pública à luz da teoria da hospitalidade :um estudo de caso

In the present time, public organizations are employing more and more solutions that uses information technology in order to ofer more transparency and better services for all citizens. Integrated Systems are IT which carry in their kernel features of integration and the use of a unique database. These systems bring several benefits and face some obstacles that make their adoption difficult. The conversion to a integrated system may take years and, thus, the study of the adoption of this IT in public sector organizations become very stimulant due to some peculiarities of this sector and the features of this technology. First of all, information about the particular integrated system in study and about its process of conversion are offered. Then, the researcher designs the configuration of the conversion process aim of this study the agents envolved and the moments and the tools used to support the process in order to elaborate the methodology of the conversion process understood as the set of procedures and tools used during all the conversion process. After this, the researcher points out, together with all the members of the conversion team, the negative and positive factors during the project. Finally, these factors were analysed through the Hospitality Theory lens which, in the researcher opinion, was very useful to understand the elements, events and moments that interfered in the project. The results consolidated empirically the Hospitality Theory presumptions, showing yet a limitation of this theory in the case in study

Motivação e satisfação à luz do modelo ASH: estudo de caso em indústria de alimentos

Neste estudo, foram examinadas as relações existentes entre a motivação e a satisfação do trabalhador no espaço laboral. O estudo empírico foi conduzido em uma única etapa, por meio da qual buscou-se conhecer as dimensões latentes identificadas e, a partir das dimensões validadas, buscou-se estabelecer relações com características motivacionais, como antecedentes, e satisfação pelo trabalho realizado, como conseqüência do atendimento das necessidades manifestadas pelo trabalhador. Foram entrevistados 38 (trinta e oito) funcionários da empresa Água Mineral Cristalina, incluindo-se os que ocupam cargos de chefia. Como instrumento de coleta de dados, foi utilizada parte do complexo da Auditoria do Sistema Humano ASH, criado por Quijano (1999), que se trata de um modelo de pesquisa na área de Psicologia Social, incluindo a Administração de Recursos Humanos, que analisa os processos psicológicos e psicossociais nas organizações. Para esta pesquisa, foram utilizados dois formulários sugeridos pelo autor citado, (anexos 01 e 02). O primeiro denomina-se condições para a motivação , com 15 (quinze) questões do tipo likert. O segundo, "trabalho bem feito e satisfação de necessidades", tem 22 (vinte e duas) questões, também do tipo likert. O instrumento foi respondido por colaboradores, independente da posição hierárquica, em aproximadamente 10 (dez) a 15 (quinze) minutos. A aplicação foi realizada diretamente pelo pesquisador nas unidades de produção e de administração da empresa. Por meio de modelagem de equações estruturais, foi estabelecido um modelo de relações causais entre as dimensões latentes relacionadas à motivação e o desempenho do empregado quando tem satisfeitas as suas necessidades. Quanto ao tratamento dos dados, este ocorreu de forma quantitativa. Quanto à análise, aconteceu após os dados terem sido tratados. Nesta pesquisa, os dados foram analisados por meio de estatísticas descritivas, atualizando-se os recursos de softwares específicos como Statistic ou SPSS Statistic Package for Social Sciences. Usou-se a técnica de Análise de Regressão, na qual foi utilizado o método STEPWISE que inclui na equação de explicação de uma variável dependente somente aquelas que auxiliam ou incrementam sua explicação. Como variáveis dependentes, foram utilizadas as variáveis do formulário "trabalho bem feito e satisfação de necessidades" e como variável independe as variáveis do questionário "condições para motivação". Sob o ponto de vista prático, este estudo mostrou que um determinado conjunto de características motivacionais influi positivamente na satisfação do trabalhador, que poderá realizar um trabalho bem feito; do lado teórico, a pesquisa verificou explicitamente a hipótese de que os aspectos motivacionais contribuem para que o empregado, sentindo-se satisfeito, desempenhe melhor as atribuições que lhe são conferidas

Ciencias Sociais, Xeografía e Historia. 'Ciencias Sociales, Geografía e Historia'.

Programación didáctica para el área de Ciencias Sociales, Geografía e Historia. Se pretende que el alumno asuma la comprensión de una realidad social rica y compleja; organizar e interpretar los conocimientos resultado de la reflexión de la sociedad sobre sí misma; adquirir un conocimiento de la realidad humana y social desde una perspectiva global e integradora que tiene como objetivo último facilitarle la comprensión de las sociedades del pasado y del presente y ser capaz de analizar los fenómenos sociales desde un punto de vista objetivo y crítico. Este área adolece de una fundamentación epistemológica global, puesto que la forman varias materias con su propia coherencia interna cada una, por lo tanto es preciso concebirla como lugar de encuentro de materias que coinciden en su fin: el estudio objetivo de los hombres y mujeres en sociedad. Una de las funciones de los centros de enseñanza es la de transmitir la cultura propia de la sociedad en la que están inseridos y, por lo tanto, la Geografía, la Historia y el Arte de Galicia deben proporcionar el marco adecuado para entender, comparar, criticar y mejorar el conocimiento de lo propio y de lo ajeno: la reflexión sobre la identidad cultural propia genera la capacidad de comprensión de otras culturas.
